Hello, I am using LVM2 whith XEN All of my DomU disks are one or more logical volume For exemple /dev/vg0/lv1 For the moment when i want do a domU backup, i take a snapshot, do an image (dd gzip) of the snapshot, delete the snapshot and restor the dd image on the original logical volume. so Backuping lvcreate -s -L500M -nlv1.snap /dev/vg0/lv1 dd if=/dev/vg0/lv1.snap bs=16M | gzip | dd of=/lv1.gz bs=16M lvremove /dev/vg0/lv1.snap Restoring gzip -dc /lv1.gz | dd of=/dev/vg0/lv1 This method is very weight and not useful ideally dd if=/dev/vg0/lv1.snap of=/dev/vg0/lv1 should be perfect but it is impossible because when restoring snapshot on the original volume, the snapshot continue to increase until to become fully and inactive Is there a solution to deactive the cow (copy and write)for during the restoration about snapshot to original volume ? <table> <tr> <td></table> <img src=http://www.lippi.fr/img/eco.jpg> Ce message et toutes les pieces jointes sont etablis a l'attention exclusive de ses destinataires et sont strictement confidentiels. <a href=http://www.lippi.fr/disclaimer.php>Pour en savoir plus cliquer ici</a> This message and any attachments are confidential to the ordinary user of the e-mail address to which it was addressed and may also be privileged. <a href=http://www.lippi.fr/disclaimer.php>More information</a>
